摘要
通过对杜仲叶中次生代谢物含量的测定，对其生长积累动态作了以下有关分析：不同无性系的次生代谢物含量差异显著：绿原酸在略１中含量最高（４０７％），略４９中含量最低（１２７％）；桃叶珊瑚甙在略１中含量最高（３９８％），略４９中含量最低（１０８％）；京尼平甙酸在灌３中含量最高（０１２％），略４９中含量最低（００５％）；总黄酮在略１１中含量最高（１６７％），略４１中含量最低（０１８％）；杜仲胶在略１中含量最高（３８０％），略０中含量最低（１７６％）；表明树木的遗传基因（决定个体生长发育）也是调控次生代谢产物的重要因素。在年周期中，杜仲叶次生代谢物生长积累的动态变化为：绿原酸含量以６月、１１月份最高，５月份最低；桃叶珊瑚甙在６月、１１月份含量最高，７月、８月份最低；京尼平甙酸在６月份含量最高，５月、１１月份最低；总黄酮以５月份含量最高，１０月份最低；杜仲胶含量以５～６月份最高，以后逐渐下降。似乎与树体年生长速率存在一定的相关关系。
Through determining the contents of secondary metabolites(active constituents)in Eucommia ulmoides Oliv.(Duzhong)leaves, it is found that secondary metabolites appear dynamic accumulation trend. \ \ Variance analysis of the contents of secondary metabolites is notable in different clones.The result illustrates that the inheritable gene is an important factor in regulating the formation of secondary metaboiltes. \ \ In the growth season of Duzhong leaves, the contents of chlorogenic acid and aucubin are highest in June and November.The content of geniposidic acid is the highest in June,too.The content of flavonoids,however,is the highest in May.The content of gutta percha is the highest in May and June,then decreasing gradually.It seems that correlation exists between dynamic accumulation of secondary metabolites and tree growth rate.
